Exploring Map Projections: Mollweide vs Mercator

Compare Mollweide, Mercator, & equal-area projections with standard parallels & stretching for accuracy. Includes Waldseemuller's globe & Goodes Homolosine. Explore VP & tangent projections with varying standard parallels. Try the applet & view Earth/Moon from Mars Rover.

Presentation Transcript

  1. Map Projections

  2. A head on Mollweide’s projection with the standard parallel at the Equator (top). It is also plotted on Mercator’s cylindrical projection (center) and on a cylindrical equal-area projection, each with two standard parallel’s at 30 degrees N& S.Scale is accurate, or true, on a standard parallel and stretched or compressed on the other parallels.

  3. Waldseemuller’s peeled globe

  4. Goodes Homolosine

  5. Projection 1 VP at Center Tangent at 0 Standard Parallel at 0

  6. Projection 2 VP at Antipode Tangent at 0 Standard Parallel at 0

  7. Projection 3 VP at Antipode Secant at 45 Standard Parallel at 45

  8. Projections applet http://www.uff.br/mapprojections/mp_en.html

  9. Earth & Moon from Mars Rover
